A Times Square drug kingpin nabbed in an “around-the-clock” crack-peddling operation is back on the streets of the Big Apple — thanks to former President Joe Biden, The Post has learned.

Johnny Perez, a 32-year-old convict nicknamed “Ghost,” was one of nearly 2,500 convicted federal criminals who had their sentences commuted by Biden on Jan. 17 before he left office — including at least three other dealers busted with him in 2021, records show.

Federal prison records show that Perez, who was one of eight suspected drug dealers rounded up in a raid by the NYPD and federal agents, is listed as due for release in May — but he is no longer behind bars.

Authorities called the brazen, $10,000-a-week crack operation a “24-hour open-air bazaar operating in around-the-clock shifts at 43rd Street and Eighth Avenue.
